9 and 11 Black Abbey Street (including 1 Jacob Street) and associated boundary walls and setted access

This is a house and a pair of back-to-back cottages, including a first-floor workshop, with a former cellar dwelling, built between 1839 and 1844 for Joseph Lang. The property stands at the corner of Black Abbey Street and Jacob Street, adjacent to an altered mirror building that is not included in the listing.

The building is constructed of buff sandstone with a Welsh slate roof. Number 9 is a double-pile house with a passageway to the right and a spine stair, while number 11 is a single-depth property, with a single-depth cottage (number 1) and a cellar to the rear.

The north-facing front elevation is watershot (painted in 2020) and has two bays per house. The left side has two stacked windows, and the right side has a doorway with a squared surround (ground-floor openings were boarded in 2020 at number 11 and replaced at number 9). Number 9's doorway has an overlight transom with a moulded modillion cornice. The eaves feature stone gutter-corbels.

The gabled west wall is also watershot in diminishing courses, with only number 1 painted. Central to the gable is a set of stacked doorways on the party wall, accessed by three stone steps, with a put-log for a hoist above. There are three stacked windows to the right; the cellar window is blocked, and the others are replacements.

The rear (south) wall is two-and-a-half storeys high, with stone gutter-corbels. Number 1 has a possible blocked doorway to the left on the first floor, and two windows with a blocked doorway to the right on the ground floor. Number 9 has a basement-and-ground-floor rear outshut constructed from random-coursed stone and raised in brick.

Inside number 9, the original floor plan is retained, including a stone stair, wide early 19th-century floorboards, chimney breasts, some doors, and hinges. The attic and cellar were not inspected. Number 1 retains its layout, stone stair, plank doors, a cellar accessed by stone steps with stone shelves, and a range fireplace. Number 11 was not inspected (except for its attic), and the cellar to number 1 was not inspected. The roof structure for numbers 11 and 1 is made from machine-sawn timbers.

Subsidiary features include a rear garden wall displaying blocked openings for former rear ashpits and coal bunkers. The setted back street also forms part of the listed item, although it's under different ownership.
